[2] Before 1874, in response to the need to provide opportunities for learning English through the medium of the mother tongue of the various races, two schools were built in Singapore, one at Cross Street and other at Kampong Glam.

The working arrangement between Pearl's Hill School and Outram School continued up to January 1953 whereas the working agreement between Outram and Raffles Institution ceased with the Japanese occupation of Singapore in February 1942.

Subsequently, this school suffered a direct hit during World War II, and with it went all Outram's past records, from 1906 to 1942.

With the conversion, the school motto was changed from "On to Success" to "Labor Omnia Vincit" – Labour Conquers All.
